Introduction

Postal is a Craftbukkit plugin dependant on Citizens2. It is a messaging system making it possible for Minecraft players to communicate with one another using the book and quill, written book item. These written communications may span worlds. Postal is an animated postal presence that may be added to any Minecraft town, settlement or mailroom. Chests are used as residence mailboxes as well as mail storage in local post offices.

Postal Crew

Citizen2 based NPC’s are the Postal crew. They are the postmen spawned and dispatched by Postal. These NPC postmen walk regular routes in towns serviced by Postal post offices. A central post office connects all of the local post offices by teleporting a NPC worker called the PostMaster from town to town, or world to world. This central NPC continually monitors and moves out of town mail to the appropriate destination. The local NPC postman takes it from there. Pickups and deliveries are done on foot, cheerfully. They know how to open and close doors, and they are a wonder on stairs. They are polite.

Addresses

Postal has a two part address system it uses to plot the location of the mailbox it services, as well as define the post office that services the address. A typical address looks like this:

<PostOffice [Address]>

Postal commands generally accept addresses as one word, or two words. If one word is indicated as an address, it is assumed that the subject is a post office. A two word address is a complete address indicating a specific residential mailbox.

The exceptions to this rule of thumb are commands that imply a residence but accept a two word address specifying the post office. /setaddr is an example of this. Invoked with a one word parameter implies that the one word is an address name and Postal is to choose the post office.

There is no built in limit on how many post offices a server may have. The Postal system typically traverses worlds.

New post offices and addresses are created and deleted on the fly. These addresses and post offices are part of a tightly written, hierarchically-structured database. This database is designed to meet the requirements of a dispatcher bent on getting mail delivered efficiently. The post man likes to walk around the town when there is nothing better to do, but get out of his way if there is mail to pick up or deliver.

Geo-Aware

Postal always knows what post office or address you are close to when invoking commands and will be as helpful as possible to relieve you of name details. This help is contextual in nature which makes it possible to use commands without any parameters simply based on your location. Complimenting this ease of use is a command-confirm system that makes it possible for Postal to safely attempt to complete complicated names with just a few characters. This is because you have an opportunity to confirm the completed command with a single ‘/’. If the command didn’t come out right you can simply try again without confirming. For Towny users, Postal always knows when it is on Towny soil and will defer to Towny hierarchy. All appropriate Postal commands are Towny aware and try to accommodate what Towny players need when used

Creating Addresses

The geographic awareness built into Postal makes it easy to create new addresses. To define a new address the only parameter required is the name you would like to use since Postal will automatically find the closest post office for you. Designing the route for the postman is even easier because Postal will figure out everything based on where you are standing. On a new address you will be teleported to the servicing post office, the beginning of the route, and given a compass pointing to your address. A modern HUD display is included to provide helpful stats while clicking on waypoints. Once you double click the final waypoint the postman will automatically appear using the route you just defined to initialize your mail box.

Finding Addresses

  • / TLIST Short for town-list, will present the player with a formatted, alphabetical list of towns when entered without parameters. The closest 3 towns, in order of distance, are also shown. If entered with enough characters to identify a particular town, the addresses of that town are listed.
  • / ALIST Short for address-list, will list the addresses of the closest town when entered without parameters. Like /tlist, it will list the addresses of a particular town if entered with enough characters to identify it. The two commands complement each other including details that the other doesn’t.
  • / PLIST Short for player-list, lists the closes 8 players, in order of distance when entered without parameters. Along with the listed player is the Postal address he/she is closest to with the compass heading required to get there. If entered with enough characters to complete a player name, Postal will list any Postal addresses or post offices owned by the player.
  • / GPS Lists the closest 8 post offices or addresses with their respective compass headings when entered without parameters. /gps may also be given the name of a post office, or an address pair to set your compass to this location.
  • / GO Teleports to Postal locations. The type type of location is determined by the number of parameters entered. Entered with no parameters assumes the central post office. One parameter assumes a local post office or town. Two parameters indicates a full residential address. Complicated names are automatically completed, and full named locations, as completed by Postal, are displayed for confirmation before teleportation. These location types may be secured or require owner permission to use.
  • Dynmap Postal uses Dynmap if it is installed. All addresses and post offices are plotted and labeled. The active routes and post man locations are shown in real-time.

Navigation

Your compass is calibrated to line up with the standard, Minecraft coordinate system when listing headings with the above commands. These are the same compass directions shown when pressing [F3]. So, with your calibrated compass and the distance and heading combination from the list, you have what you need to navigate to it. This is the way compasses are normally used outside of Minecraft. The benefit of navigating to a destination is that you remain aware of where you are in relation to all the listed destinations, as well as other distance and heading destinations received from other plugins ie: GPS, Pplot and gpsTowny.

Mail and Shipping

Postal letters are based on the written book item. This book will handle up to 50 pages of written correspondence. Item shipping is done with single chests. The two commands used for this have the built-in address finding and completing capabilities described above. Indicating desired addresses is done with the minimum amount of typing. The two commands are: /addr <PO [Address]> and /package <PO [Address]>

On servers that have economy turned on, both of these commands tell you the price of the postage or shipping and give you a chance to confirm it.

Once addressed, letters may be put in any accessible Postal mailbox, and Postal will take it from there. Shipments involve the creation of a shipping label which may be mailed like any letter. Once packaged, the shipment is sign-sealed and indestructible until the post man picks up the shipping label. The post man removes the chest at that point for transport to the recipient.

The recipient of a shipment may refuse the shipment. If refused, the shipment is returned to the sender.

Mass mailings sent to entire towns, even worlds are available to administrators, Towny mayors and post office owners. The /distr command facilitates this.

Capacity Management

Full mail boxes are managed. If the chest is full, the postman will delete the oldest junk mail if he finds one. If that doesn't create the room he needs, he will look for a non-book to delete. If unable to find room in a mailbox, the postman will continue trying to deliver until successful. Mail is otherwise held at the local post office.

Bulk distributions available to post office owners, Towny mayors, and administrators are sent with an expiration date. Regular information mailings therefore do not back up and become undesired clutter

Dispatcher

The NPC dispatcher provides regular coverage and route-walking, oldest next. This dispatcher is also preemptive in that it recognizes mail waiting to be delivered or picked up. The dispatcher manages the route walking schedule to favor actual mail movement over route-walking, or postal presence. Both the post men and the PostMaster are preemptively dispatched to keep the mail moving efficiently.

Chunk Manager

Postal has a chunk manager that monitors chunks required for postal routes. These chunks are automatically loaded and kept loaded. This makes it possible for NPC's to continue doing their job when there is no player in sight. NPC's have a tendency to go to sleep when no player is around. This chunk manager also facilitates the control of spawning monsters on Postal routes. There is a switch in the config file that controls this. By default, Postal routes are kept monster free.

WatchDog

Postal has an evolved watchdog, monitoring system. The Postal workers are vigilantly monitored. It is capable of respawning a NPC worker if something happens to it. It can restart itself if needed. Mail is always backed up. A Server crash or NPC griefing should not result in lost mail. The Citizens NPC’s are pretty reliable on their own.

General Notes

The Bukkit versioning that started early December 2012, applies to all plugins that go outside the Bukkit api to reach the Minecraft api. This started with 145.R1, the first recommended build for 145.

Coincidently, and the cause for much confusion here, The Bukkit api was expanded to include dealing with Book and Quill items. Pre 145.R1 Postal does go beyond the Bukkit api to deal with written books because it has to. Post 145.Ri uses the Bukkit api instead and is therefore exempt from the Bukkit versioning restrictions.

There are only two versions of Postal, delineated by an api improvement not a versioning requirement.

Citizens2 Note: At Citizens build 762 the NPCs underwent navigational, speed refinement. As this relates to Postal there is a modest speed change. It causes the NPCs to move a little slower. It can trigger watchdog activity by Postal since the NPCs don't seem to be on schedule. The fix is simple. Just change the Speed setting in 'Config.yml' from 1.0 to 1.2

    My version is technically working on my local CraftBukkit 1.7.5 server that I play with my two younger siblings (all three clients are 1.7.4 running Optifine, if that matters). Actually, everything that the plugin advertises is working - unlike everyone else, apparently. The only real problem is that the plugin eats memory like a fat person eats donuts until the server is constantly spitting out OutOfMemory errors and I keep getting kicked for no reason. I don't have any other Citizens plugins, and all of the other plugins are pretty lightweight - at least, they have never slowed down the server more than a couple of seconds while it's starting or reloading. I have three questions: what is causing this, how can I fix it, and do I have to wait for an update? I reeeeaaally want to be able to use this, because it's much more realistic and cool-looking than Courier, the mailman plugin I'm using at the moment.

    We need a "report" feature for plugin developers that don't seem to test their plugins... Not working. :(

    yes, i've the same problem. I hope there will be an update for it, because the server is unusable if postal is started

    Everything seems to have been set up fine, but i keep getting errors that say something like "Dispatcher Time Out, Restarting" and then the whole server restarts.

    Any idea what's causing this and why? it only seems to have started since 1.7, because i had it working fine on 1.6.2.

    I get an error "Dispatcher Not running" whenever I try to do things in Postal. Any Ideas?

    Would be awesome if this still worked, after placing a chest or double chest then typing /setcentral does nothing to the chest. like /setlocal or /setaddr puts a sign on the chest but not central? also had to remove denizen to even get it that far, using newest releases of everything.

    -Edit Got it working, if you run the add-on "Jail" don't try to use postal inside of the jail. denizen still glitching
